The electronic unit and drainage
and overflow protection
– Drainage protection
Any leaking water is collected in the
sump in the base of the machine.
A float switch closes the solenoid
valves , preventing any more water
from flowing into the machine and
water in the suds container is pum‐
ped away.
– Overflow protection
If the water level exceeds a certain
level, the drain pump switches in
and pumps the excess water away in
a controlled manner.
Should the water level rise repeatedly
in an uncontrolled way, the drain
pump will switch on continuously,
the washing machine will indicate
that there is a fault and a tone will
sound.
Drain hose
The drain hose is protected by a venti‐
lation system which prevents the wash‐
ing machine from being emptied com‐
pletely.
